As far as installing Flash into Konqueror specifically, you shouldn't need to do it. As long as Konqueror knows where your Firefox plugins are installed (/usr/lib/mozilla/plugins on a VL box), it can find them and use them. To set up the plugins for Konqueror, click on Settings -> Configure Konqueror -> Plugins -> Scan for New Plugins. Konqueror will scan for whatever plugins you have in the paths listed in the search dialog and will use what it can.
